Article Citation - WoS: 10The Relationship of Loot Box Engagement To Gender, Severity of Disordered Gaming, Using Mmorpgs, and Motives for Online Gaming(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2021) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayObjective: The main aim of the current study was to evaluate the relationship of loot box engagement to gender, disordered gaming, using massively multiplayer online role-playing games (MMORPGs), and motives for online gaming among young adults. Methods: The cross-sectional online study was conducted with 752 volun-teer participants in Turkey. The participants were assessed with the nine-item Internet Gaming Disorder Scale - Short Form (IGDS9-SF) and the Motives for Online Gaming Questionnaire (MOGQ). Results: The age of participants who engage with loot boxes (n=171, 22.7%) was lower than the group who do not engage with loot boxes (n=581, 77.3%). Also, of the male using microtransaction, buying games, time spent on the gaming, gaming more than usual on weekends, being an e-sport gamer and/or following e-sport, having problems related with gaming, using MMORPGs, the severity of IGD symptoms, and all six types of motives for online gaming were higher in the group who engage with loot boxes. Age at first gaming did not differ between the groups. In the logistic regression model, loot box engagement was related to the severity of disordered gaming, using MMORPGs and severities of skill development and competition motives for online gaming. Conclusion: These findings suggest that those who engage with loot boxes may be using MMORPGs more with the motives of skill development and competition and they may have higher severity of IGD symptoms. Thus, this group of gamers who engage with loot boxes should be considered as a risk group and interventions should particularly include these individuals.Article Citation - WoS: 16Citation - Scopus: 16Measuring Dysfunctional Grief Due To a Covid-19 Loss: a Turkish Validation Study of the Pandemic Grief Scale(Routledge Journals, Taylor & Francis Ltd, 2022) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayThe global death toll to date of the COVID-19 pandemic has been enormous, and millions of people are grieving these losses. The aim of the current study is to validate a Turkish version of the Pandemic Grief Scale (PGS), which is a brief English-language mental health screener to identify probable cases of dysfunctional grief associated with a COVID-19 death. Participants were assessed using the PGS, Patient Health Questionnaire-4 (PHQ-4) and Work and Social Adjustment Scale (WSAS). We surveyed 758 Turkish native speakers who participated online. Confirmatory factor analysis showed that the factor structure of the PGS was satisfactory. The scale was internally consistent with a Cronbach's alpha of 0.77 and a composite reliability of 0.90. The PGS demonstrated construct validity with strong correlations with suicidal ideation and substance use coping. Positive correlations of the PGS with the PHQ-4 and the WSAS demonstrated adequate convergent validity. The PGS discriminates well between persons with and without dysfunctional grief using an optimized cut score of >= 3 (89% sensitivity and 72% specificity). The PGS also demonstrates incremental validity by explaining most of the variance (43%) in functional impairment due to a COVID-19 loss beyond measures of depression and generalized anxiety. These findings closely replicate the original validation study on the PGS in English and suggest that the current Turkish version of the PGS is a valid and reliable measure to assess the severity of dysfunctional grief associated with a COVID-19 death.Article Citation - WoS: 161Citation - Scopus: 156Measuring Anxiety Related To Covid-19: a Turkish Validation Study of the Coronavirus Anxiety Scale(Routledge Journals, Taylor & Francis Ltd, 2022) Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Evren, CuneytThe aim of the current study is to validate the Turkish version of the Coronavirus Anxiety Scale (CAS). Participants were assessed across the CAS, Obsession with COVID-19 Scale (OCS) and Fear of COVID-19 Scale. We surveyed 1023 Turkish native speakers who participated online. Confirmatory factor analysis showed that the factor structure of the CAS was satisfactory. The scale was internally consistent with a Cronbach's alpha of 0.80. Positive correlations of the CAS with the OCS and the Fear of COVID-19 Scale demonstrated adequate convergent validity. These findings suggest that the CAS is a valid and reliable measure to assess the severity of dysfunctional coronavirus related anxiety.Article Citation - WoS: 1Development and Psychometric Validation of the Turkish Gambling Disorder Screening Test: a Measure That Evaluates Gambling Disorder Regarding the American Psychiatric Association Framework(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Topcu-bulut, MerveObjective: First study aims to develop the Gambling Disorder Screening Test (GDST), a standardized measure that assesses symptoms and prevalence of gambling disorder (GD) regarding the American Psychiatric Association (APA) diagnostic framework. The aim of the second study is to validate the GDST psychometrically. Methods: In the first study participants were assessed with GDST. Sample comprised of 400 Turkish university students and video game players (54.0% male, mean age 24.30 years, SD=6.83) that was enrolled online. In the second study the sample (n=326; 60.1% male, mean age 23.54 years, SD=4.44) was similar with the first study. Participants were assessed with GDST, the South Oaks Gambling Screen (SOGS) and the Gambling Motives Questionnaire (GMQ). Results: In the first study, according to the exploratory factor analysis a single component accounted for 64.02% of total variance. The scale was internally consistent with a Cronbach's alpha of 0.93, thus considered as reliable. In the second study, confirmatory factor analysis showed that GDST's factor structure (i.e., the unidimensional structure) was satisfactory. Positive correlations between GDST and the number of self-reported gambling type, SOGS and GMQ scores demonstrated adequate convergent and criterion-related validity. Also the GDST had a Cronbach's alpha of 0.92 in this sample. Conclusion: These findings from Study 1 and Study 2 suggest that the Turkish GDST is a valid and reliable measure to assess the severity of GD related issues according to APA's framework among young adults and for the purposes of early detection of GD in clinical settings and research.Article Citation - WoS: 25Citation - Scopus: 28The Impact of Depression, Anxiety, Neuroticism, and Severity of Internet Addiction Symptoms on the Relationship Between Probable Adhd and Severity of Insomnia Among Young Adults(Elsevier Ireland Ltd, 2019) Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayThe aim of the present study was to evaluate the impact of depression, anxiety, neuroticism, and severity of Internet addiction symptoms (IAS) on the relationship between probable attention deficit/hyperactivity disorder (ADHD) and severity of insomnia among young adults. The study was conducted with online survey among 1010 volunteered university students in Ankara, people who are in the e-mail database of a company located in Istanbul that organizes e-sports tournaments and Turkish garners from gaming forums. Scale scores were higher among the group with high probability of insomnia (n = 200, 19.8%). Also risk of high probability of insomnia was 2.7 times higher among those with probable ADHD. In linear regression analysis, both inattentiveness and hyperactivity/impulsivity dimensions of ADHD were related with the severity of insomnia, together with severities of anxiety, depression, neuroticism and IAS. Similarly, presence of probable ADHD was related with the severity of insomnia in ANCOVA, together with severities of anxiety, depression, neuroticism and IAS. These findings suggest that the presence of probable ADHD and the severity of ADHD symptoms are related with the severity of insomnia, even after controlling the depression, anxiety, neuroticism and IAS, which are all related with the severity of insomnia, among young adults.Article Citation - WoS: 36Citation - Scopus: 45Relationships of Internet Addiction and Internet Gaming Disorder Symptom Severities With Probable Attention Deficit/Hyperactivity Disorder, Aggression and Negative Affect Among University Students(Springer Wien, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayThe aim of the present study was to evaluate relationships of Internet addiction (IA) and Internet gaming disorder (IGD) symptom severities with probable attention deficit/hyperactivity disorder (ADHD) and aggression among university students, while controlling the effects of anxiety and depressive symptoms. The study was conducted with online survey among 1509 volunteered university students in Ankara who regularly use the Internet, among whom we conducted analyses related with IA. Among these students, 987 of them, who play video games, were included in the analyses related with IGD. Correlation analyses revealed that the severities of the scale scores were mildly correlated with each other both among students who regularly use the Internet and students who play video games. Probable ADHD was associated with the severity of IA symptoms, together with depression and aggression, particularly physical aggression and hostility, in ANCOVA analyses. Similarly probable ADHD was also associated with the severity of IGD symptoms, together with depression and aggression, particularly physical aggression, anger and hostility, in ANCOVA analyses. These findings suggest that the presence of probable ADHD is related with both severity of IA and IGD symptoms, together with aggression and depression.Article Citation - WoS: 49Citation - Scopus: 53Relationship of Internet Addiction Severity With Probable Adhd and Difficulties in Emotion Regulation Among Young Adults(Elsevier Ireland Ltd, 2018) Kutlu, Nilay; Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, MerveThe aim of the present study was to evaluate relationship of Internet addiction (IA) symptom severity with probable attention deficit/hyperactivity disorder (ADHD) and difficulties in emotion regulation, while controlling the effects of depression, anxiety and neuroticism. The study was conducted with online survey among 1010 volunteered participants of university students and/or amateur or professional gamers. Scale scores were higher among the group with high probability of ADHD (n = 190, 18.8%). In linear regression analysis, both Inattentiveness and hyperactivity/impulsivity dimensions of ADHD were related with the severity of IA symptoms, together with depression and non-accept dimension of the Difficulties in Emotion Regulation Scale (DERS). Similarly, presence of probable ADHD was related with the severity of IA symptoms in ANCOVA, together with depression, neuroticism and non-accept dimension of DERS. Participants were two different groups of non-clinical samples and all scales were self-rated. Also common comorbidities were not screened. Finally, since this study is cross-sectional the findings of this study cannot address the causal relationships among the primary constructs of interest. These findings suggest that the presence of probable ADHD is related with the severity of IA symptoms, together with the difficulties in emotion regulation, particularly non-accept dimension, depression and neuroticism among young adults.
